2 Claims. (Cl. 134-11) This invention relates to textiles, and is conof various types of fabrics, which may be in the cerned primarily with the application of a mateform of piece goods, such as woven or knitted rial to fabrics to impart crease-proofing or piece goods that may be made from cotton, linen, crush-proofing properties, as well as a permasilk, rayon or other artificial cellulose fibres,

However, the finishing material to the yarn prior to weavthe use of such synthetic resins requires a fairly ing or knitting into the ultimate fabric.

While preferred specific embodiments of the invention are hereinbefore set forth in detail, it is to be understood that I am not to be limited to the exact compositions above enumerated because various modifications of these details may be provided in putting the invention into practice, within the purview of the appended claims.

I claim:-

1. A dilute liquid textile finishing material of the character described, consisting of a solution which consists of a solvent for sucrose acetate and a sucrose acetate together with a softening agent for sucrose octa-acetate, the sucrose acetate and softening agent each being present in proportions ranging from 1 to 5% of the solution.

2. A dilute liquid textile finishing material of the character described, consisting of a solvent for sucrose octa-acetate, and sucrose octa-acetate, together with a softening agent for sucrose octa-acetate, said sucrose octa-acetate and softening agent being present in equal amounts and in a proportion ranging from 2% to 5% of the entire solution.
